Before starting the installation, gather the necessary tools and materials to ensure a smooth process. Here’s a list of what you will need:
- Aftermarket headers
- Socket set
- Ratchet and extensions
- Torque wrench
- Gasket scraper
- New gaskets
- High-temperature sealant
- Safety glasses
- Gloves
Preparation Steps
Before you begin the installation, it’s essential to prepare your workspace and vehicle. Follow these steps:
- Park the vehicle on a flat surface and engage the parking brake.
